Calculate the molar conductivity of acetic acid at infinite dilution. Given that molar conductivity of `HCl. CH_(3)COONa` and NaCl is 426.1,91.0 and 126.5 `ohm^(-1)cm^(2)"mol"^(-1)` respectively.

A

`390.6ohm^(-1)cm^(2)"mol"^(-1)`

B

`195.3ohm^(-1)cm^(2)"mol"^(-1)`

C

`585.9ohm^(-1)cm^(2)"mol"^(-1)`

D

`292.95ohm^(-1)cm^(2)"mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A
The degree of dissociation
`(a)=(^^_(m)(CH_(3)COOH))/(^^_(m)(CH_(3)COOH))=(11.7)/(40.9+394.1)=0.03`,
